When the joint table does not contain a valid entry, the decoding restarts from scratch. By implementing the trick of jumping to the 2nd level of the individual table (and inlining the whole), a speed improvement of 5-10% is possible. On a 1000-frames YUV4:2:0 video, before: 362851 decicycles in 422, 262094 runs, 50 skips 182488 decicycles in gray, 262087 runs, 57 skips Object size: 23584 Overall time: 8.377 After: 346800 decicycles in 422, 262079 runs, 65 skips 168197 decicycles in gray, 262077 runs, 67 skips Object size: 23188 Overall time: 7.878 Signed-off-by: Michael Niedermayer <michaelni@gmx.at> |
